AUTOMATIC STARTING-VALVE.

Specification of Letters Patent.

Appheamn filed May 5, 1908. Serial No. 30,904.

T all whom it may concern:

Be it known that I. Josnrn B. Lam, a citizenot' rne Ynited States, and a resident 'of 'Glenwood Landing. in the county of Nasan and State of Xew York. have invented a new and Improved Automatic Starting Valve, of which the following a full, clear. and exactdescription.

This invention relates to certain improvements in mechanism for controlling the pressure in conduits. containers and the like. and more particularly relates to that type of controller in which the flow of fluid through one conduit. for i-natante. a motive tluid for operatii-ig; a-punip, is controlled by the pres sure in a separate conduit or container. for instance, air con'ipreseed by a pump operated by said motive liuid. The controller may be used in various ditl'erent systems and mechanisms where itis desired to i'nz'iintain a substantially uni'torin fluid pressure.

Reference is to be had to the accompanying' drawings. forming a part of this specification. in which similar characters of re't' erence indinte) iiorreaponding parts in all the figures, and. in which Figure l is a sectiinrthrough one form of device embodying my invention; Fig. an end view thereof; and Fig. 3 is a aide elevation of a portion of a pumping system. illustrating-one use to which my improved valve may he put. f

In the specific construction illustrated in the aecoi'npanying drawings. I provide a conduit 10. having a ljialanced valve for controlling; the flow of fluid therethrough. This valve preferably coinpri. a valve casllfhaving two valve sex 12 and two 'aives 13 mounted on illL" fdlIli. valve stem l-l. for siinnltaneouslyengaging with both seats. The valve seats and the connecting partition .5 carrying the same. are so arran ed that one of the valvefi opens toward rhesiipply end of the conduit and the other GllBls tovra'riil the deliver end, 0 that vcr. 'le force re '=;,iired ,toopen the valve. h gh the tiuiil ill ill conduit be under ry lililli ";-i.:-'1"6. the valve caning is eyed at one Sit'ii a threru'lcd plug; i

' packing (nu-rounding the i l 1i. which extends to the i1 carriw at its outer or .on l. opera"ling in a small .,l or the phlOl'l being: we phere and the opposite (L- 1 131G433; one in.

o the atn '18 by a suitable framework,

side of the piston being exposed to the pressure of the syatem in connection with which my improved controller is used. The cylinder 18 is formed integral with an inlet 24). controlled by an outwardly-opening valve 21, and. an outlet 22 controlled by an outwardlvopening valve 23. The valves El and 23 are both carried b v a valve stem 24-. which extends. throu 'h a packing 27 to the exterior oi. the device.

The valve carsing it in operatively connected to the casting forming the cylinder including two standards :26. ach secured at one end to the plug 16 of the valve casing 11, and connected at its upper end to the sides of the cylinder 18. in addition to the standards '26, I provide a third standard 27, which is also connected to the plug 11. but terminates short of the cylinder. The. three standards are connected together adjacent the plug by a platform or bas c 28, movable longitudinally oi the standards and normally held again rt movement by suitahle nuts 2 threaded on said standards. The standards are connected toge her adjacent the upper end by a suitable trzmsverse frame 30. including a fulcrum ll. in alinement with the end ol lhe standard 27. The valve stem l/l extends; through the fulcrum or baee 28, and carries a collar 32. Between the collar and bane and engaging with. both. I mount a coil spring 3 which normally tends to lift the balanced valve from ita acct and force the pin on inao the c vlinoer. Above the collar. l provide a lever 34-. ai'lz-ip ed to rest on the till-"run: 3-1. and adapted to also engage with the end. at the valve stem 24.. The lever may. if dcsaired carry a regulating stop or contact ment with said valve stem.

To illustrate more clearly the operation of my improved valve. T. have shown in Fig. 3,

a portion of a pun'iping system having my valve need in connection tl'iercwith. The

1-35 for controlling the engage- To set the valve the operator pushes upward on the lever 34 to'open the valve 21 'and close the valve 23. The pressure in the tem is transmitted through the conduit 41 to the piston 17 and operates in opposition to the spring 33 to hold the valve 13 to its seat. Through the fulcrum and the lever3 l, it

' also holds the valve 23 closed and the valve 21 open. If, for any reason, the pressure in the system should drop below the predetermined limit, the spring 33 Will open the valve 13 and start the pump, the valve 21 will close, and the valve 23 will open'l This shuts off communicationbetween the pressure system and the piston 17 and the pump will operate continuously until the operator resets the valve. The valve operates automatically to start the pump and Will keep up the pressure until the cause of the drop in pressure or the trouble on the main pump, is attended to. p f

The valve is especially designed for use with -an auxiliary pump which is normally out of operation and only comes into operation automatically upon the failure of the main pump.

I Having thus described my invention, 1 claim as new and desire to secure by Letters Patent:

1. In combination, a conduit, a valve for controlling the same, means for retaining a fluid under pressure, the pressure being dependent, on thefiow or: fluid through said conduit, a piston exposed to said fluid under pressure and operatively connected to said valve to hold the latter in closed position when said fluid exceeds a predetermined limit, and a' valve for terminating the application of fluid pressure to the piston upon the opening of .said first mentioned valve.

2. In combination, a conduit, a valve for controlling the same, means for retaining a fluid under pressure, the pressure being dependent on the flow of-fluid through said conduit, a piston exposed to said fluid under pressure and operatively connected .to said valve to hold the latter in closed position when said fluid exceeds a predetermined limit, and a valve for open ng commuter. tion between said piston and the outer atmosphere \upon the opening of the for mentioned valve.

3.111 combination, a conduit, a valve for controlling the same, means for retaining a fluid under pressure, the pressure being dependent on the flow of fluid through said. conduit, a piston operatively connected to said valve and exposed to said fluid under pressure, and a valve operated by said piston and controlling the application of fluid pressure thereto.

4:. In combination, a conduit, a valve for controlling the same, means for retaining a timid under pressure, the pressure being dependent on the flow of fluid through said conduit, a piston operatively connected to said valve and exposed to said fluid under pressure, a valve for controlling the application of fluid pressure to the piston, a lever having pivotal connection with said piston,- a stationary fulcrum, and means connecting the opposite ends of said lever to said lastmentioned valve.

5. In combination, a conduit, a valve for controlling the same, means for retaining a fluid under pressure, the pressure being de pendent on the flow of fluid through said conduit, a piston operatively connected to said valve and exposed to said fluid under pressure, a valve for controlling the appli-,

cation of'fiuid pressure to the piston, a standard adjacent the first-mentionedvalve, a spring acting inopposition to said piston, a fulcrum carried bysaid standard, a lever having pivotal connection with said piston and in engagement Withsaid-fulcrum, and

means connecting the SGCOllClflllGIltlOllGClYa lve to said lever,

In testimony whereof I have signed. my
